Yet to all who received him, to those who believed in his name, he gave the right to become children of God- children born not of natural descent, nor of human decision or a husband’s will, but born of God. John 1:12-13.
Because you are sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba, Father.” So you are no longer a slave, but a son; and since you are a son, God has made you also an heir. Galatians 4:6-7.
